This is all good advice; I'd add that a Simulator would be useful for the first time RC hobbyist. I got one (FMS) for free after I'd already banged up the Champ pretty good. I know it would have given me the reflexes I lacked when first flying the plane.
Another topic would be Weather. Don't fly in the wind, at first; smallish 1 oz. airplanes are a lot like dry leaves. The slightest breeze does funny things to them.
The little monster is very forgiving; it's so light that it resists damage. And the damage you sustain is easier to repair. I remember taking it out the 5th or 6th time, and commenting to a friend who came along that I was pleased with myself; it was the first time I'd managed to keep it in the air for more than a minute or two. A short while later, when I landed it, his dog ripped it to shreds. Even utterly destroyed, the Champ was made flyable again with some Gorilla glue and tape, though it's a bit lopsided and flys funny. Bashing it into the ground, buildings, trees, my girlfriend's head, etc. has only added character to it. It's a great little plane.
